1 0' aZZ when it may camera: 1 h

Be it kn own that I, CARL WO'LFF, a subject of the King of Wiirtemberg,and a resident of the city of NewYork, borough of Manhattan, in thecounty and State of New York, have invented a new and Improved Machinefor Cutting Glue, Gelatin, and other Substances,

of which the following is a full, clear, and ex;

act description.

My invention relates to machines for cutting glue, gelatin, and othersubstances, and has for its object to provide a simple and veryefiicient machine for the above-indicated purpose.

The invention Will be fully described hereinafter and the features ofnovelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the views.

Figure 1 is a sectional elevation of my improved machine on the line 1 1of Fig. 2, and Fig. 2 is a plan thereof with parts broken away. 7

The machine comprises a mechanism for feeding the blocks or cakes ofglue or gelatin, a cutting mechanism, aconveying mechanism for carryingaway the cut slices, and suitable devices, such as drying-frames, forreceiving the material from said conveying mechanism.

The feed mechanism consists of two endless belts A A, passing overrollers a, a, journaled in the parallel walls B of the machineframe, thebelts being of such width as to eX tend substantially fromone of saidwalls to the other. The receiving-belt Ahas an approximately-horizontalportion A followed by an incline A while the other belt A projectsupwardly beyond the belt A, so as to form a stop for the material and toassist in directing it into the downward channel C, formed between theopposing approximatelyvertical runs of the belts A A. A throat is formedat about the center of said channel by mounting the guide-rollers a on aspringpressed bar or support D, the tension of the spring 1) beingcapable of adjustment by means of a nut D The material fed down thechannel 0 is adapted to be cut into slices by means of a series ofknives E, connectingthe walls B and arranged stepwise; as shown,

'so that the knives will begin to cut one after the other and not alltogether. From the knives E theslices are conveyed downward bysuperposed inclined belts F, which differ in length, as shown, so thattheir lower ends are approximately in the same horizontal plane. Thematerial at the lower ends of the belts F passesonto a series of beltsG, located side by side (not superposed)'and as a rule mechanism. Asshown, the shaftofone of" the rollers a of the belt A may be adriveshaft actuating the upper roller 0.. ofthe belt A by means of acrossed belt J. The lower roller a of the beltA has a gear connection Kwith the roller for the upper end of the adjacent belt F, and all thebelts F arecornpelled to move in unison by a chain L, enga ingsprocket-wheels on the upper rollers. The belts G are driven by a pulleyM on the shaftat the delivery end of said belts and a belt N, whichconnects said shaft with one of the shafts of the conveyer H.

In'operation the material passes from the horizontal portion 'A to theinclined portion A and to the throat of the channel 0, where the twobelts A and A take a firm hold of the material and feed it forciblydownward against the knives or blades E. As these knives are arrangedstepwise, with their cut ting edges forming an oblique line transverseto the path of the material, it follows that the material will beengaged first by the upper knife only, then by the next knife below, andso on, each knife beginning to cut only after the nextknife above hasentered the material. With this arrangement the material is littleliable to slip or bulge, and the power required to operate the machineis comparatively low. The resistance to the cutting action of the bladeis much greater at the beginning of the cut than after the knife hasentered the ma at the the proper time by an attendant, who

also replaces the empty screens at the opposite end of the conveyer H;

clined belts the upper ends of which are located adjacent to theknives,while their lower ends are approximately at the same level, and aseries of conveying-belts located side by side and arranged at an angleto the plane of the first-mentioned belts, each belt of the secondseries beingin receiving relation to one of the belts of the'firstseries.

5. The combination of the vertical knives arranged stepwise, mechanismfor feeding the The machine is simple, compact, and very eflicient.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. The combination with the feed mechan, ism,of a cutting-device comprising a plurality of blades arranged stepwiseand located inthe e path of the material laterally of each other,

' carried away from the blades as soon as it is cut, independently oftheother slices.

2. The combination of the vertical knives arranged stepwise, andsuperposed inclined I belts whose upper and receiving ends are 10-catedadjacent said knives and-whose delivery ends are approximately atthe same level.

3. Thecembination of the knives arranged stepwise, the belts each of,which has its re ceiving end located adjacent a knife, and the series ofconveying-belts each of which is' arranged with its receivingendadjacent the delivery end of one of the first-mentioned belts. and atan angle to the plane of the same.

4. The combination of the vertical knives arranged'stepwise,mechanismfor feeding the j 1 material to the knives, the superposed in-;

V material to the knives,the superposed inclined belts the upper ends ofwhich are located adjacent to the knives, while their lower ends areapproximately at the same level, a series of conveying-belts locatedside by side and arranged at an angleto the plane of first-mew tionedbelts, each belt of the second series be ing in receiving relation toone of the belts of the first series, and a conveyor located 11nandaplurality of inclined belts,eachof which has its receiving end adjacentone of the blades, whereby each slice of the material is Y the channeltermed by the parallel vertical runs. a

In testimony whereof I have signed. my name to this specification in thepresence of two subscribing witnesses.
